Amazing talk by Jason Podrabsky (@OregonStateU) as part of the Life Sciences Seminars at MU, on the incredible stress tolerance of annual killifish (Austrofundulus limnaeus) embryos! These tiny survivors endure extreme conditions that would kill most other life forms

7 basic science discoveries that changed the world
Ozempic, MRI machines and flat screen televisions all emerged out of fundamental research decades earlier — the very types of study being slashed by the US government.

Husbandry of N. furzeri, the shortest-lived vertebrate used for biogerontology, is dependent on bloodworms. When our protocol is followed, you can feed N. furzeri an open-formula purified diet — paving the way for more consistent and reproducible lab studies. #killifish @thefsbi.bsky.social

Jedna z našich nejvzácnějších a nejkrásnějších rybek, sekavčík balkánský. Byl znám pouze z jedné říčky při hranicích se Slovenskem. V r. 2016 byla nalezena velká populace v řece Jihlavě. To jen podtrhuje důležitost ichtyologických monitoringů

An interesting reading. Dietary restriction is intensively using mice as a model. Wheatley et al suggest that mouse physiology may considerably confound the real effects of dietary restriction, meaning that mice may not be the ideal model for studying DR

We published a visual guide to the repertoire of hepatocyte alterations recognized in Nothobranchius furzeri, a vertebrate model in aging research. Giant mitochondria and intense hepatocellular vacuolation are the most prominent features. #killifish

Larger species have a higher cancer prevalence than smaller species, according to a study that refutes Peto’s Paradox, the claim that that species’ body size is not correlated with cancer risk. In PNAS: www.pnas.org/doi/10.1073/...

Vedení univerzity je jistě nelehká věc a zaslouží adekvátní ohodnocení. Ale nevím, jak často si “řadový” akademik přijde na odměny v řádu vícenásobků jeho mzdy. Ale je třeba prijem nasobit, když je 175 tis kč/měs?
